CLOUDSTACK-5147: Removing basic and sg tag from the test case which should not be run on basic zone setup

component.test_project_limits.TestMaxProjectNetworks.test_maxAccountNetworks tries to create multiple guest networks in an project of account which is not possible in basic zone as there is only one guest network allowed per zone in basic zone setup.
Hence removing the tags basic and sg so that this test case won't be picked up to run on basic zone setup.
